To a-,ZZ'whom 'it may. concern Be it known that I, EARL V.- VComisroiv,a citizen of' the United States, resident of Cleveland, county ofCuyahoga, and lSta-te of Ohio, have inventedanew and useful lmprovement4in Stoves, of which the following' is a specification, the-principle ofthe inventioir being.v herein explained and the best mode in which Ihave contemplated applyiIl-g" that principle, soas to distinguish 'itfrom other inventions. p My invention relates to stoves and par- Yticularly to that class Aof stoves in'which the oven is heated by meansof products Ofcombustion of gaseous fuel or`by means of the radiated rconvected heatderived from the combustion of coal such as are shown,described and claimed in my Patent No. 1,032,816 issued July 16, 1912.

The object f the invention is to automa-tically control communicationbetween the interior of the ovenand the exterior thereof. y My saidinvention consists of means hereinafter fully described and particularlyset forth in the .claims.

' The 'annexed drawing andthe following description 'set forth in detailcertain means embodying my invetion, ,the disclosed means, however,constituting but one of various `mechanical forms in which the principleof the inyention may be applied.

ln said annexed drawings z-Figure 1 represents a fragmentary, transversevertical section'of a stove embodying my invention. Fig. Ql-represents alongitudinal vertical sectionof such stove.

In the illustrated embodiment of my invention -A represents the mainouter frame of the stove and B the lire-box of the same locatedlaterally of the oven C. Suitable provisionis made for carrying thegases of combustion from the hre-box B around .the oven' ,and out of theusual outlet-Hue or smoke-pipe D. By .these means the oven may beheatedby means of these gases in the usual manner.

As in the above patented device, in the front of -the stove is located achamber in which is placed a gas burner E. Covering this chamber" andextending rearwardly of the bottom of the oven is the deflector F alsoas in said previously patented device, provided with the lateral and endoutlets f, f from which said gases may enter into the main portion ofthe interior of the oven.

vNear the bottom and in one'side ofthe oven municating with walls is theusual outlet opening c which is connected with the outlet 4 duct` Cwhich leads in the usual o'r any suitable "manner to the-smoke pipe oroutletduct D. Located at the mouth of this duct however, is `a-valveor'damper Gr, which is adapted-toclose by gravity; and cover the mouthof the duct C' and interrupt communication between the latter and the'oven.'` This valve has formed thereon a projection or extension g whichlies in the-path of lan inclined plane 7a2-suitably secured to the sideof the deflector This plane is located in a position such thatv lwhenthe deflector is in its normalposition .within the oven the lug g willoccupy a position'such as to raisethe valve or. damper Gr and thuspermit communication to be established between the interior of the ovenand the duct C. This is the position which the parts occupyA when thecombustion of gas is used for the purpose of heating the interior of theoven, the products of' such combustion passing out through the duct C as-will be readily understood. When, however, it is not desired to usegas, but to use coal for the purpose of heating the oven, the deiiectorF is removed, whereupon the mouth of the' duct C becomes automaticallyclosed, as a result of the dropping of the valve G, so that during theheating process, the heated air confined in the oven cannot escapetherefrom as is'the case in an ordinary stove. When the gas is in usethe chamber E is preferably covered byineans of'a suitable plate (notshown). y A

By means of the above described construction it will be seen that theinterior of the oven is automatically arranged to lend itself to the useof either .coal ors gas as a fuel,l by the Imere removing or replacingof the deflector F.

i Having fully described my invention, what l claim and desire to secureby Letters Patent is 1. In a stove, the combination of an oven; a sourceof heated gas communicating therewith', a detached member adapted to bemoved into or completely'removed from the interior of said oven; anoutlet-flue comthe latter; and -meansperated by said detached member'forestablishing or disestablishing suchlast-named communication.

' 2. lIn a stove, the combination of an' oven; a source of heated gascommunicating therewith; a member adapted'to' be moved into- ,or removedfrom said. oven flue; saiddeliector being Aadapted to automaticallyoperate said valve to close or open as it' is respectively removedv orreplaced in said oven'.

4. In a stove, the combination of an oven; a source of heated ascommunicating therewith; an outlet-figuey also gommunicat-ing with saidoven; a-delector for such gas and removable from said oven; and a valveadapted to interruptv such communication an outlet-Hue' and -to assumefan "interrupting 'position by gravity; said valve provided with a lugorextensionprojecting,v when in said position, into the path. ofmovement of said defiector.

5. In a stove, the combination of an oven; a source of heated ascommunicating therewith; an outletue also communicating with said oven;a deflector for such gas and removable from said oven; adapted tointerrupt such communication and to assume an interrupting position bygravity; said deiector being provided With an inclined surface, and saidvalve with a lug or projection lying in the path of movement thereof.

Signed by me, this 2nd day of January, 1913. l
